PURPOSE:To measure safely and easily the viscosity of a high-temp. melt by providing a capillary outflow pipe at the bottom of a sample container made of aluminum, hanging the container on a weight measuring device by using a suspension wire, and measuring the sample viscosity by the weight variations per hour of the sample flowout quantity from the outflow pipe. CONSTITUTION:A sample container 4 made of aluminum providing a capillary outflow pipe 7 at the bottom is hung on a weight measuring device 10 on a stand 1 by a platinum heat resistant and anticorrosive wire 9 which hangs the holes 8, 8 around the periphery of the upper mouth of the container 6 and put in a measuring pipe 3 surronded by an electric furnace 2. A thermocouple 12 is inserted into the measuring pipe 3 and the weight variation and the temp. at the time when the sample in the container 6 flows out are recorded on a recorder 11. The weight variation per hour of the sample is obtained and the viscosity is calculated by an analytical curve made by the sample whose viscosity is previously known. Thus, a low-melting point alloy is not made from the sample containing heavy metals such as Sn, Pb like the ash generated from an electric dust collector and the viscosity measurement can be carried out in an atmosphere generating a harmful gas such as SOx, HCl. |
